The F5 Prefix now supersedes the previous F3 and F4 series prefixes due to the smoothing of the Pressure Coefficient (Cp) curve for cruise and landing/stall speeds. There are enough numbers to go around. You do not have to plot all of them to make a smooth airfoil curve, unless you want to.

Multiply the Percent values (X,Y) given below by the chord length you desire.
